Technical field
This utility model is related to technical field of mold, more particularly to a kind of for processing special copper pipe of the profile with rectangular channel
Mould.
Background technology
Special copper pipe of the profile with rectangular channel is the blank for making particular cable joint, and this product is to its axial length
Required precision it is general, but to its radial direction be the size on cross section required precision it is very high.It is required that groove must prolong axle uniform.It is recessed
Should be full at the top of two shoulder of groove, and on the outside diameter hoop of tubing, it is not allow for subsiding, the defect such as fillet.The two sides of groove should
It is parallel to each other, and it is vertical with bottom land plane.
The main method of realizing of such product is that main pipe (common copper pipe) is pressed the specific length of particular cable joint at present
Intercept, then the product is obtained through wire cutting or Milling Process.With the shortcoming of this production method be product quality stability it is poor
And production efficiency bottom, a kind of mould for processing special copper pipe of the profile with rectangular channel is we have proposed for this, for solving
The problems referred to above.
Utility model content
The purpose of this utility model is to solve shortcoming present in prior art, and the one kind for proposing for processing outward
The mould of special copper pipe of the shape with rectangular channel.
To achieve these goals, this utility model employs following technical scheme：
A kind of mould for processing special copper pipe of the profile with rectangular channel, including external mold and internal model, in the external mold
Portion is provided with die cavity, and the internal model is located in die cavity, and one end of the internal model is connected with core bar, and the die cavity includes feed zone, mistake
Cross deformed area, shaping region and discharge zone, the feed zone, transition deformation area, shaping region, discharge zone along copper pipe feedstock direction successively
Arrange, the perisporium of the feed zone is in bell mouth shape along the opposite direction that copper pipe feeds, and the perisporium in the transition deformation area is along copper pipe
The opposite direction of charging is in funnel-form, and the equidistant annular of perisporium in the transition deformation area is provided with double wedge, the double wedge in ligule simultaneously
Extend to feed zone, the cross section of the shaping region is circle, and the perisporium of the discharge zone is in funnel-form along copper pipe feedstock direction.
Preferably, the external mold is truncated cone-shaped structure.
Preferably, the external mold is formed in one with double wedge.
In this utility model, feed zone Main Function is that guiding main pipe smoothly enters transition deformation area, transition deformation area
Main Function is the shape for changing main pipe, completes the setting of work piece radial direction；Shaping region Main Function is finishing work piece
Radial dimension；Discharge zone Main Function is to protect the surface of work piece and mould sizing injury-free；This utility model institute
Using die cavity, particularly shape in the uniqueness in transition deformation area so that main pipe in deformation process, from starting just to allow the recessed of tubing
Groove is formed and the compression tube reducing of external diameter keeps synchronous, is radially acted on to compressive stress by two all the time, so as to ensure that special pipe square
The filler of the two sides of shape groove and drift angle is abundant, then the finishing through sizing area ensure that product reaches standard requirement, product matter
The stability of amount, production efficiency and stock utilization are all significantly increased.

Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only this utility model a part of embodiment, rather than whole
Embodiment.
Reference picture 1-3, a kind of mould for processing special copper pipe of the profile with rectangular channel, including external mold 1 and internal model 7,
The middle part of external mold 1 is provided with die cavity, and internal model 7 is located in die cavity, and one end of internal model 7 is connected with core bar 8, and die cavity includes feed zone 2, mistake
Deformed area 3, shaping region 4 and discharge zone 5 is crossed, feed zone 2, transition deformation area 3, shaping region 4, discharge zone 5 are along copper pipe feedstock direction
Set gradually, the perisporium of feed zone 2 is in bell mouth shape along the opposite direction that copper pipe feeds, and its conical surface oblique angle is 8-14 °, feed zone 2
Main Function is that guiding main pipe smoothly enters transition deformation area 3, and the perisporium in transition deformation area 3 along the opposite direction that copper pipe feeds is in
Funnel-form, 3 Main Function of transition deformation area are the shapes for changing main pipe, complete the setting of work piece radial direction, transition deformation area 3
The equidistant annular of perisporium be provided with double wedge 6, double wedge 6 is in ligule and extends to feed zone 2, the cross-sectional width of double wedge 6 and height edge
The opposite direction of copper pipe charging is gradually reduced, and disappears to intersection of the feed zone 2 with transition deformation area 3, and the cross section of shaping region 4 is
